Findings and limitations Industry implications Related developments

What changed

Regeneron reported Phase 1/2 results for investigational CIDEBsiRNA in 40 adults with MASLD: 30 received active treatment and 10 placebo. At week 36, liver fat fell 58–80% across dose groups versus 2.9% with placebo. Safety was the primary objective; liver-fat measures were secondary. One serious hyperglycemia event was considered unrelated; longer-term histologic outcomes remain under evaluation.

Why it may matter

These early human findings may support further development of genetics-guided siRNA therapies; histologic benefit and long-term safety still require confirmation.

The interpretation above is analysis, not a conclusion attributed to the original source.

Elebsiran–tobevibart meets Phase 3 hepatitis delta endpoint in ECLIPSE 1

Vir reported topline results from 124 adults in ECLIPSE 1. The siRNA–antibody combination achieved undetectable HDV RNA plus normal ALT in 44% at Week 48, versus 0% in delayed-treatment controls at Week 12; 79% had undetectable virus. One Grade 3 treatment-related neutrophil decrease occurred. These are company-reported investigational results with different comparison timepoints.

SOLSTICE update reports prolonged HDV suppression and exploratory treatment-free follow-up

Vir reported undetectable HDV RNA in all 28 SOLSTICE participants completing 96 weeks of elebsiran–tobevibart. Separately, 10 eligible patients stopping treatment achieved sustained viral response at 12 weeks; seven reached 24 weeks and one reached 48 weeks. The exploratory stopping analysis lacks a formal data cut, has incomplete safety follow-up, and does not establish cure.

ARO-DIMER-PA shows dual lipid lowering in early human study, with dose-related safety findings

Arrowhead reported Phase 1/2a interim data involving 21 ARO-DIMER-PA recipients and 10 placebo recipients. Across dose cohorts, mean LDL-C fell 26%–65% and median triglycerides fell 56%–78% from baseline; these were not placebo-adjusted effects. Injection-site erythema occurred in 20 treated participants, and one participant receiving 400 mg experienced Grade 3 syncope. Cardiovascular outcome benefit remains unestablished.
